FUEL CELL AND FUEL CELL STACK

摘要

A fuel cell (10) includes an electrolyte electrode assembly (26) and a pair of separators (28) sandwiching the electrolyte electrode assembly (26). Each of the separators (28) is a single plate, and includes a plurality of circular disks (36). First protrusions (48) and second protrusions (52) are provided on both surfaces of the circular disk (36). The first protrusions (48) contact the anode (24) of the electrolyte electrode assembly (26), and the second protrusions (52) contact the cathode (22) of the electrolyte electrode assembly (26). A channel member (56) is provided on a surface of the separat or (28) facing the cathode (22). The channel member (56) forms a plurality of fuel gas supply channels (66) connected between a fuel gas supply passage (3 0) and a fuel gas inlet (54) for supplying a fuel gas into a fuel gas flow fiel d (46).
